Hey everyone. I was hoping someone could help. I went to flash the new 2.2 ROM but when I enter any commands in the command prompt for flashboot it just stays on waiting for device. It never goes anywhere. I checked the drives in device manager and it shows I am using Android bootloader interface. Any assistance is appreciated. I am using Win 7 if that matters.

OS: Ubuntu 12.04

Are you running fastboot as root? Sometimes fastboot does weird things if it's not running as root
moved thread to QA where it belongs......surprised this was in Dev tbh......
Dear XDA Geniuses,
I have a 16gb Nexus 7 WI-Fi. I was using Nexus 7 toolkit 2.0.0 to try and flash my nexus 7 back to the the stock google rom (option 9 in the toolkit.) It seems as if it wiped out cyanogen mod 10, which i had been using, as well as clockwork recovery. My nexus 7 now boot up with the google logo and the unlocked padlock on the bootom. using the volume rocker i can select the bootloader option and get an android figure with his chest open.
this is the only option i can select. my attempts have been:
1)connect it to computer. Windows 7 and Windows 8 will not recognize it, nor let me access it from the command line.
2. Use nexus 7 toolkit, which DOES recognize it in fastboot mode, to flash a new recovery on there. it says that a command failed, and won't let it write to it.
3) install adb and android sdk tools. my tablet won't show up under devices, and I am not sure if it is still in usb debugging mode. command line will not recognize it as an adb device and will not control tablet.
when i looked at this thread it was dealing with a locked bootloader, while mine is unlocked. it also wanted command line operations from the computer, which does not seem to work for me.
i was attempting to do something like this (laptop mag blog how to hard reset a bricked nexus 7) but without my nexus 7 showing up under devices I am not sure what my options are.
TLDR: Nexus 7 16gb WIFI only boots into boot recovery. Using nexus 7 toolkit to recognize as fastboot. otherwise will not show up on computer. no recovery, no boot image.
Thank you for reading.
I went back and reread the thread on flashing and restoring nexus 7 to stock in this forum, but every command I try returns " command write failed invalid argument ". Using android sdk manager i can get it to recognize the device in fastboot mode. my drivers there seem to be working.
edit: I got all the way to flashing the bootloader, but it returned "no such device or address. "

latest progress can be found at imgur slash TAikq
now it is say data transfer failure - too many links. 146.84 seconds.
it was my cable. the cable mounted it in fastboot mode, but would not allow writing. switched out the cable, and we are up and running again. thanks!
Um.... Glad we could help?

Sticky?
Man, I would love to see this sticky posted, or at least a list of errors and fixes stickied. I have been looking for an answer to the same issue for two days. Finding out it was just a lousy cable really really really pissed me off... I'm glad someone figured it out and actually posted their solution, most of these wind up with nothing.
OMG, I've tried to flash my N7 with a new lollipop 5.1 today and got the same issue as described here http://forum.xda-developers.com/showthread.php?t=2724273 then, after 5 or 6 hours of thinking what is going on, I finally found this very old thread and guess what? Changing this sh***ty cable I was using solved the problem.
Use USB ports on the back of your computer, not the front.
Hello all,
I poked around and saw some similar issues, but nothing quite like what I am facing and was hoping you all could help me.
I woke up this morning to find my nexus 7 2013 32 gig wifi only on the "Google" logo loading screen. The tablet will not boot up into android.
I read up a little bit and found that I can factory reset using adb and fastboot...but here is my problem...USB Debugging is not enabled on my tablet, and I cannot access android to turn it on. Therefore, adb is not recognizing my device. If I try to enter recovery from the bootloader screen I get the same "Google" logo.
My bootloader is locked.
Really hoping someone who knows more than I about how these things work can help.
Thanks in advance for any assistance you can provide.
This is the 2012 forum you need the Nexus 7 2013 forum

You will have to do it with fastboot commands, since adb isn't available when you can't get into recovery or Android.OS. Send the fastboot oem unlock command to unlock your bootloader, and follow the sticky fastboot thread directions.

Thanks. I appreciate the insight. However, when I run that command it gets to erasing the user data and then just hangs. It never moves on. I assumed this was because debugging is turned off, but I could definitely be wrong.
Any ideas on how to get past this step?

Its not because of usb debugging but its also not good. It may be corrupted nand (internal memory unwritable). Unexplained failure to boot followed by fastboot commands failing or hanging are typical hallmarks of this. Do you still have a warranty?

Unfortunately, Captain Sweatpants is probably correct. I'm also guessing corrupted NAND or a corrupted bootloader.

Okay so my brother got an update for his nexus 7 to 5.1 I believe it was. Anyways for whatever reason the update has failed and the tablet will no longer load up to android. Just gets stuck on the boot up screen. I can access fastboot and recovery mode but recovery is saying no command and my pc doesn't recognize the nexus 7 so using adb doesn't seem to be an option. I've gone through and updated all the drivers needed to see the tablet. I'm wondering how in the world do I factory reset this thing? I'm like at a loss so if you can help much thanks to you.
Hello, a year back I had a problem of hardware in my tab, after restoring the hard ware the service center person installed a mobile version of OS.
the tab was ok but when I tried to install a system update, while install I got a error and from then the tab never starts it stuck at the X symbol.
I have tried to reboot the device by doing boot cache clear option, not worked.
I tried by using the adb as well the I am getting the message Verification failed.
As I am not able to use my tab I could not set the USB debug mode.
Can any one please help me in the above issue.
I've heard of a problem with the flash component becoming corrupt after so long. It could be that but did you try fastboot commands on your computer to see if it shows the device?

Hello ZionFreak,
Thanks for your response, yes I have tried with adb devices command which don't show any device, I have downloaded the Nexus tool kit, when I tried to unlock the device it says that no device is recognized. Please help me in solving this issue.
